The system works with the magnetic resonance coupling method of the transmitter and receiver and almost does not require human intervention. The peculiarity of the system is that the receiver can be factory mounted under the electric car, and the transmitter under asphalt. That is, to charge an electric car, it will be enough to park it in an equipped parking lot – the energy to power the battery will be transmitted through the air gap between the devices.
Currently, the power of the prototype is 11 kW with energy transfer within 300 mm. In the future, devices with a power of up to 50 kW should appear, the charging time of which does not exceed one hour. A 300 kW charging station is also planned to be developed, which will allow the electric bus to be fully charged in half an hour.
“During production, the first box (receiver) is installed under the electric vehicle, the second (transmitter) is placed under the road surface, energy will be transmitted through the air gap between them to power the battery. In practice, this means that it will be enough to park the car on the transmitting magnetic system and it will automatically start charging,” he said.
